Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from iptfs’ call to skbput during the recombination process for non-linear skb objects, potentially...

CVE-2026-31517: Missing Release of Memory after Effective Lifetime

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: fix skbput panic on non-linear skb during reassembly In iptfsreassemcont, IP-TFS attempts to append data to the new inner packet 'newskb' that is being reassembled. First a zero-copy approach is tried if it succeeds...

GHSA-F984-PCP8-V2P7 Wasmtime has improperly masked return value from `table.grow` with Winch compiler backend

Impact Wasmtime's Winch compiler backend contains a bug where translating the table.grow operator causes the result to be incorrectly typed. For 32-bit tables this means that the result of the operator, internally in Winch, is tagged as a 64-bit value instead of a 32-bit value. This invalid...

crypto/x509: Quadratic complexity when checking name constraints in crypto/x509

A potential denial of service flaw has been discovered in golang's crypto/x509 module. Due to the design of the name constraint checking algorithm, the processing time of some inputs scales non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary...

CVE-2026-34987

Wasmtime is a runtime for WebAssembly. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime with its Winch baseline non-default compiler backend may allow properly constructed guest Wasm to access host memory outside of its linear-memory sandbox. This vulnerability requires use of the Winch...

encoding/pem: Quadratic complexity when parsing some invalid inputs in encoding/pem

A potential denial of service flaw has been discovered in the golang encoding/pem module. Due to the design of the PEM parsing function, the processing time for some inputs scales non-linearly with respect to the size of the input. This affects programs which parse untrusted PEM inputs and may...
